The ability to separate parts from media must be taken into consideration early in the development of the finishing process. Keep in mind that media wears down and should be periodically screened to remove undersized media pieces that can jamb holes.
If one piece of equipment is intended to be used for many jobs, a rotary screen separator would be the closest to a universal machine.
If height space is limited due to low clearance, a flat bed screen separator can be made to fit in a space as small as ten inches high, whereas a rotary screen separator requires a minimum of thirty to forty inches in height.
If limited length space is available, a rotary screen separator can be used since, due to its greater efficiency, it is half the length of a flat bed screen.
If long, thin parts need to be separated, a slotted screen material works best.
If a very small screen opening is required, but a durable material is needed, choose a wire mesh.
If an accurate opening size is needed, perforated metal would be the best choice.
If a crevasse or pocket must be reached, but a large media is necessary to provide the pressure to abrade, use a machine with screens stacked end-to-end or one screen on top of another, allowing multiple items to be separated in one pass.
